The way google will nag you when your storage is nearly full is ultra annoying, borderline dark pattern. It will warn you that you might be running out of storage when attaching small PDFs to an email and the like, when you still have hundreds of megabytes available.
I started using Immich just this week and am very impressed by the amount of features built-in and everything just works. It really is a full-on replacement for google photos which is amazing. Even advanced features like face-detection using AI and partner sharing are there.
Shout-out also to immich-go [1] which is a cli tool that allowed me to migrate hundred of gigabytes of photos from a google takeout backup flawlessly.
